gcc - 无法通过 Homebrew 安装 GCC48 - curl 错误（身份验证？）

Question

我需要 c11 支持，但我似乎无法从自制软件安装 gcc48：

$ brew install gcc48
==> Downloading ftp://gcc.gnu.org/pub/gcc/snapshots/4.8.0-RC-20130316/gcc-4.8.0-RC-20130316.tar.bz2

curl: (9) Server denied you to change to the given directory
Error: Download failed: ftp://gcc.gnu.org/pub/gcc/snapshots/4.8.0-RC-20130316/gcc-4.8.0-RC-20130316.tar.bz2

Answer 1

似乎curl没有给出正确的错误，从而误导您认为这是某种身份验证问题。

真正的问题是 ftp 服务器上不存在指定的目录。也许这是一个自制的问题。

$ wget ftp://gcc.gnu.org/pub/gcc/snapshots/4.8.0-RC-20130316/gcc-4.8.0-RC-20130316.tar.bz2
